A city traffic study found people drive slower than the posted speed limit in some areas.

"Based on our studies, people will drive close to or below the speed limit," said Hector Barron, a city traffic engineer. "What we found is that 85 percent of the people are traveling at or below the limit."

In all, eight sections of roadway in Sacramento will see the speed limit drop 5 mph. For example, a section of San Juan Road from Northgate to Regency Park Circle will be reduced from 45 to 40 mph.

Other roads will see a reduction from 35 to 30 mph, or 30 to 25 mph.

Some people who live near these roads said speeding is a big problem.

"There is enough accidents around here -- I know they are not doing the speed limit," said Shawn Rutter, who lives near San Juan Road. "They speed down my street as fast as they do San Juan."

For families who walk the sidewalks or try to cross some of the streets with children, speed remains a big safety concern.

“It’s a big deal," Keyona Travis said. "I’ve lived around here for a while and I have kids, and people speed all the time."

The city has close to 400 roadways with posted speed limits.

Each section, or speed zone, has to be evaluated and studied every seven years to meet state requirements.

Of the 29 studied this year, eight sections of roadway were lowered. The rest saw no change.

A DETOUR IS AVAILABLE. NEW TONIGHT, SEVERAL STRETCHES OF ROADWAY IN SACRAMENTO HAVE SPEED LIMITS THAT HAVE BEEN LOWERED. KCRA 3'S RICHARD SHARP IS LIVE TO EXPLAIN WHY AND WHAT NEIGHBORS ARE SAYING ABOUT IT. THIS SIGN WILL SOON READ 40, NOT 45. YOU MIGHT BE SURPRISED HOW THE CITY DECIDED ON THIS REDUCTION. AND IT SEEMS LIKE A SMALL DIFFERENCE BUT FOR THE PEOPLE WHO LIVE NEARBY, IT'S BIG. ASK THE PEOPLE WHO LIVE AROUND WEST EL CAMINO. DO PEOPLE DRIVE FAST ALONG HERE? YES, ALL THE TIME. OR SAN JUAN AVENUE. IT LOOKS LIKE 45 MILES AND I SAY THEY DO AT LEAST 50 OR 60 ON THIS STREET. AND YOU'LL UNDERSTAND ONE OF THE BIGGEST COMPLAINTS THEY HAVE -- PEOPLE DRIVING TOO FAST IN THEIR NEIGHBORHOOD. THERE ARE ENOUGH ACCIDENTS AROUND THERE. I KNOW THEY ARE ARE NOT DOING THE SPEED LIMIT. WELL, NOW MANY OF THOSE SPEED LIMITS WILL BE LOWERED. FROM 45 TO 40, OR 35 TO 30 -- ONLY FIVE MILES AN HOUR. IT'S JUST FIVE MILES AN HOUR. IS THAT GOING TO MAKE A DIFFERENCE? YES, IT IS. THE REASON FOR THE CHANGE IN SPEED LIMIT IS NOT SPEEDING CARS. THE CITY STUDIES TRAFFIC ON EACH ROADWAY. WHAT THEY FOUND IS THAT ON SOME ROADS, 85% OF THE DRIVERS DRIVE SLOWER THAN THE SPEED LIMIT. MOST FOLKS WILL DRY BELOW THE SPEED LIMIT. 85% OF THE PEOPLE ARE TRAVELING AT OR BELOW. AND IN SOME CASES, THE LIMIT IS LOWERED BECAUSE OF THE OTHER FACTORS. THIS IS 35 BUT A BLOCK AWAY IT'S 45. BY REDUCING THAT SECTION TO 40 MILES PER HOUR, IT MAKES THE TRANSITION EASIER ON DRIVER TO GO TO THE 35 MILE-AN-HOUR ZONE. IN ALL, EIGHT STRETCHES OF ROADWAY IN SACRAMENTO WILL BE LOWERED FIVE MILES AN HOUR. THE CHANGE MAY BE NOTICED BY PEOPLE WHO LIVE NEARBY, BUT SOME WORRY DRIVERS WON'T NOTICE A THING. IT'S NOT GOING TO CHANGE ANYTHING. IT'S A BIG DEAL. I LIVED AROUND HERE FOR A WHILE AND I HAVE KIDS AND THEY SPEED ALL THE TIME. WHEN THE MOST INTERESTING THINGS IS THE CITY HAS TO STUDY THESE INTERSECTIONS. THEY HAVE MORE THAN 400 OF THEM EVERY SEVEN YEARS. IF THEY DO NOT, AND IF SOMEONE
